How to add, activate or authorize password less email account

So I had changed my outlook/hotmail account to password less and it deactivated my email on my iPhone15 and wanted me to re-enter the password to reauthorize the account (same as when you change the account passwords.)

After searching for a fix, I saw a few long winded workaround's. So thought I would post the short version fix.

TLDR:

if you delete the account (settings->mail->accounts) and then re-add it the iPhone will automatically set it up

….and trigger your 2 factor auth app to set it back up.
